We were blessed to have character voice master Corey Burton on hand for this test. Corey cooked up four different voices to exercise each mic — and then delivered them, one after another, damn near identically 16 times in a row.
I smile every time I hear this. Check out a typical performance (unedited!):

Test Setup and Signal Path
Corey sat in the main voice booth at the DCV studio. As you’d expect, the room is well-treated, as it was built for the specific purpose of recording voices.
Recording two at once has two benefits:
- We hear twice as many mics in the same amount of time, reducing artist fatigue.
- We can compare some mics on identical performances — a fact we took advantage of by hanging interesting pairs, e.g.: Samar #5 vs #6, Cloud JRS-34 vs. AEA R44CX, Cascade Fathead vs VinJet, Royer R122 vs. R122V, AEA KU4 vs. RCA KU3A/10001, etc.
All mics were recorded dry, through a pair of Martech MSS-10 preamps, into Apogee PSX-100 converters (at 24-bit, 48 kHz), clocked by an Apogee Big Ben master clock, directly into Pro Tools.
Randy, Ryan Canestro, and I triple-teamed the mic changes. Randy engineered. Brienne Michelle took beautiful photos, some of which you can see on this page. Corey was in charge of Vocal Awesomeness.
Corey provided background information on the four voices he’d performed for our test. (Special thanks to Randy for arranging and recording this interview!)
The line Corey performed is an excerpt from the introduction to a CBS radio show called Escape, dating to the 1940s.
“Tired of the everyday routine? Wanna get away from it all? We offer you … escape!”
That was to see how dense the sound of that placement and pitch is. It should sound really inky and heavy, on a good ribbon, without hearing a lot of transient texture.
On a condenser, that placement [the William Conrad voice] can sound strangulated. But it should sound big and warm and heavy and imposing… Arresting.
Usually it was William Conrad, or Paul Frees, very close to the microphone, seducing the listener into this mysterious world, setting the stage.
Hear William Conrad’s original (from the Three Skeleton Key episode):
William Conrad original
“Stardust, the all-fabric bleach. It beats the dingies!”
The pirate [voice] is for texture, to see if it gets that magical, rich, complex texture instead of sounding splattery. It’s the Pirates of the Carribean texture.
When pirate voices like that are recorded with a condenser, they tend to sound spitty and shallow. A ribbon will usually fill it out, and give it a roaring energy. It can sound tight and “fake-y” on anything but a great big classic ribbon.
It’s a very coarse texture. A ribbon mic makes it sound magical, instead of just … ugly.
“Live, from beautiful downtown Burbank, it’s Ribbon Mic Weekend!”
Gary Owens has that plummy, full-rounded announcer voice. I always think of Gary Owens and the RCA 44 because of Rowan and Martin’s Laugh In. It always sounded so full, springy, bouncy. [I chose this voice] to get that round, old-fashioned announcer chest tone.
And again, only a ribbon microphone gets a magical springiness to that chest tone, as opposed to the drier, more percussive chest tone that a condenser or dynamic would tend to impart.
With a mismatched microphone, that sort of placement [the Gary Owens voice] would sound hollow, instead of very chest-y and rich.
“Ladies and gentlemen, the Columbia Broadcasting System and its affiliated stations presents, Orson Welles and the Mercury Theater On The Air!”
In the original War of the Worlds broadcast, that could have even been an early dynamic microphone. Orson Welles used a dynamic microphone a lot. But then his voice was a little heavy for a ribbon… an early [RCA] 44 or 77A would have been a little too thick, I would think.
They’re all old-timey voices, because that’s what I associate with classic ribbons. What I want to hear in a modern ribbon is something that lends a similar type of magical quality, but cleaner, so that it passes inspection with modern ears.
Those nasal-toned announcers, with the little swoops of delivery — that sort of swooping soaring thing, it’s sort of like a frequency-response evenness test, to my ear, because those swoops should be even [in] volume. Instead of surging, it should all sound … like it’s compressed.
Randy gain-matched the Mercury Theater clip, then output full-resolution WAVs, which I converted to 320kbps MP3s via lame. That’s what you’ll hear below.
To hear the other three voices Corey performed — the William Conrad line, the pirate soap commercial, and the Gary Owens line — and to hear the head-to-head comparisons of each mic pair we recorded, grab the full session here.
Interview with Corey Burton
Randy and Corey chatted about the session. We’ve transcribed part of the interview here, and we’ll post the original audio soon — it’s well worth listening to, just to hear Corey demonstrate the voices he’s describing.
RC: Of all the mics, what were the ones that stand out?
CB: I was most interested in the [AEA] KU4, which did not disappoint. But then again it was not quite as flavorful as its predecessor, the [RCA] KU-3A. It was great, but not something I would use without EQ, without enhancement, to do something meant to sound old-timey. It had all the right qualities, but sounded modern.
Probably the standout was the one I cannot remember the name of, the ones with the ultra-powerful magnets?
RC: Samar Audio.
The Royers were outstanding.
RC: What differentiated the Royers from each other?
CB: The [R-122V] tube had a little more character. The solid-state [R-122] was flatter, more clean, more natural. Both excellent. Not particularly colorful, but really good. A little EQ, and either one of them could be used in so many ways.
I did prefer the tube for voice. It just had a little more ribbon-y flavor, more of a character thumbprint to it. The Royers are modern and clean sounding for ribbons, but excellent.
RC: I also remember you enjoying their low-cost ribbon [the Royer Labs R-101].
CB: I love that. Because that did have — it wasn’t like an RCA flavor. In fact it wasn’t exactly like any old ribbon that I’ve heard. I guess [it was] closest to a Reslo as far as overall character and flavor. Not in response curve.
RC: How would you characterize a Reslo?
CB: It’s zippy. It’s got a nice, metallic — in a good way, metallic — resonance to it. Exciting. It’s sort of like an aural exciter.
[The R-101] kind of did that all by itself, adding an exciting enhancement to voices. It didn’t sound unnatural, but more of a condenser-y kind of sheen on the top end, and nice and flavorful on the low end. Not muddy in any way, not tubby. But big and tasty.
To me, it came close to what a 10001/KU-3A does to voices. Just gave it some sparkle that is a part of the character of the vocal tone. It didn’t sound artificial, yet definitely something bigger than life. [It’s] not quite transparent reality, but that’s not what I want a ribbon microphone for. I want bigger than life.
Shifting placement and pitch, it’s all enhanced in an equally flattering, listenable way. A very handsome sound to the entire range of voices — I didn’t hear any weak spots in it.
Whereas the original Royer, the 121: warm, but no snap at all. No immediacy, no presence. Just rich. But the 101’s got real flavor to it. I loved it.
(That’s the end of the interview.)
I first compared the RCA KU-3A to everything else, because I wanted to understand its appeal. It is a lot brighter than many of these other ribbons, even the ones that in previous sessions demonstrated an extended top end. But it’s not just a high-frequency boost that’s happening here; there’s an undeniably cool sheen to the voice that I don’t hear on any of the other mics. It has presence. It sounds closer, crisper, more detailed, and more engaging than the other mics. The mic is bright, but I think the midrange is where the magic happens.
AEA’s supercardioid KU4 comes very close to this sound. The KU4 and KU-3A MP3 clips above are from different performances, but the session file contains a head-to-head test (from a single performance) that will let you compare them directly.
I can hear what Corey likes about the Royer Labs R-101. It’s not as glossy or open on top as the old RCA mic, and it sounds heavier in the low mids, but it has an appealing character — impressive for a relatively inexpensive microphone.
The little beyerdynamic M 130 surprised me here. I expected an unusably bass-heavy track, but in this application the mic sounds pretty slick. It’s scooped in the mids, which isn’t ideal for a voice application, but it’s a neat sound that might be just right for some applications.
The two Samar Audio Design MF65s sound great here. They’re balanced and rich, with an appealing texture in the mids and just enough low-frequency warmth. I prefer serial number 6 on the deep William Conrad voice; on the voices with more tonal range, I found both Samar mics equally nice.
The are a number of good sounds in this session; so long as you’re not trying to match the sound of Disney cartoon from 60 years ago, many of these mics would be suitable. In a subsequent, informal test on my own voice, I really liked several of the mics: Shure KSM353, Shure KSM313 (rear side), AEA R84 (rear side), Royer R-121 (rear side), Royer R-101 (rear side), Audio-Technica AT4080, Samar MF65 s/n 6, and sE VR1.
(Why did I like the rear side on so many of these mics? They either use offset ribbons or acoustic trickery to create a brighter sound on the rear side of the mic. To my ear, this brightness balanced the natural low-end (proximity-boosted) warmth of these mics. On sibilant or thinner-sounding voices, you’d want different picks than these.)
As is always the case, which of these sounds is best for your needs depends entirely on the source and the context. A close listen to the full Corey Burton session should make the sonic differences between these mics, and their relative strengths, very clear. And if there’s interest, I can post my own narration samples for further dissection and discussion.
Huge thanks to Corey Burton, whose interest, patience, and expertise made this test far more fun and educational than it would have otherwise been.
“Venti” thanks (mandatory coffee humor) to Randy Coppinger for organizing and recording this session, plus the followup interview.
Dinner is on me, next time I’m in Burbank! (But be warned, I’ll have another box of microphones with me. 😉 )
